Whether anger above all causes fervor in the heart?

❌ Objection 1 : It would seem that heat is not above all the effect of anger. For fervor, as stated above (Question [28], Article [5]; Question [37], Article [2]), belongs to love. But love, as above stated, is the beginning and cause of all the passions. Since then the cause is more powerful than its effect, it seems that anger is not the chief cause of fervor.

❌ Objection 2 : Further, those things which, of themselves, arouse fervor, increase as time goes on; thus love grows stronger the longer it lasts. But in course of time anger grows weaker; for the Philosopher says (Rhet. ii, 3) that "time puts an end to anger." Therefore fervor is not the proper effect of anger.

❌ Objection 3 : Further, fervor added to fervor produces greater fervor. But "the addition of a greater anger banishes already existing anger," as the Philosopher says (Rhet. ii, 3). Therefore anger does not cause fervor.
